'The present invention relates to automatic speed controlling mechanism for motor vehicles and is in the nature of an improve- ,tle is fully closed.

means shown ment on the speed controlling 375,961, tiled in my applicatim Serial No. May 27th. 1907. a

The object of the invention is to provide means on the motor vehicle for limiting its speed to any desired maximum rate and to securely inclose and protect. such means in such manner that they may not be tampered with, at; least without the knowledge of persons owning-or controlling the car.

I 1 i l While my invention is particularly useful in connection with commercial vehicles which are heavy and which can not he safely operated at high speed, it is also,

useful in connection with taxi ahs and pleasurc vehicles when it is desired to limit them to the maximum speeds permitted by law or regulation.

The invention will be described in connection with the accompanying drawing, in which,

Figure 1 is a side elevation of a part of a multiple cylinder hydrocarbon motor of a type commonly used in motor vehicles; Fig. 2 is a plan view of the parts shown in Fig. l, the cylinders and intake manifold being removed; Fig. 3 is a vertical section through the governor casing and adjacent parts; Fig. 4 is an end view of certain parts shown in Fig. 3; Fig. 5 is a vertical section through the motor intake pipe showing the throttle valves.

Referring to the drawing, indicates the base and crank case of a motor of a type commonly used on motor; vehicles, 11 cylin- 'ders mounted on the= crank case and 12 the intake manifold for'kconducting the explosive mixture to the various cylinders. Communicatin with the intake manifold is a mixture pipe 13 in which are located two' 1 scribed.

The valve H may he opened more or less at the will of the operator. The valve 15 stands normally open as shown in Fig. when the engine is not running. hut when the engine is running it gradually closes as the speed increases and is adapted to keep the engine running approxin'iatelv at a predetermined maxinuun speed it the flow of gas be not restricted by the manually operated valve 14. The hy-passcs and prevent the engine from being stalled or stopped by the full closure of either or both valves.

Referring more particularly to Figs. 3

and 4, 24 indicatesa shaft having fixed thereon a gear 25 which is driven from the ;crank shalt through suitable connecting 1 gears.

The shaft 24 may be used for various purposes, such as running the magneto or the water or oil pumps. It is mounted in bearings 26, 27, in a casing 28 which is prefe ably an extension of the crank case 10, the hearings receiving oil from the crank case through an-inclosed passage 29. Upon the shaft 24 is a disk 30 to which the gear 25 is secured. This disk also carries arms 31 on which are pivoted governor levers 32, the free ends of which carry weights or balls, while the'inner ends are interlocked with grooves in a block 33 which is free to slide upon a reduced extension of the shaft 24. The outer ends of the arms 31 are provided with stops, 35 for limiting the outward movement of the free ends of the governor levers.

The governor levers are normally held in the position shown in Fig. 3 by a spring 36, one end of which is arranged within an adjustable cup 37 while the other end bears upon a head 38 surrounding the forward end of the shaft 24. Inter-posed between the head 3S and the block 3?, is a thrust ball bearing 39 which permits the block 1-33 to revolve freely with the shaft 24 while, at the same time, it may exert pressure upon the nonrotating head 23S. may be adjusted by which has a notched flange 40 adapted to be locked in any desired position by a removable bracket all. A second ball thrust bearing atQ-is preferably interposed between the disk and the hearing 27 to reduce the friction caused by the end thrust exerted on the shaft 2% by the governor levers.

The head 38, which is moved in one direction by the governor levers and'in the opposite direction by the springs, is carried by a sliding rod 43 mounted in the cup 37. The forward end of this rod extends through the endoi the cup and a yoke 44 is pivotally connected to it by means of a pin 45, (Figs. 3 and t). The yoke -14: is also pivotally connected at 46 with the lower arm of a lever a7, centrally pivoted at l8. The upper end of the lever 48 is pivotally connected with a sleeve -i-9 adapted to slide on the rod 19 which operates the valve 15. On rod 19 is a fixed collar 50 and a spring 51 is interposed between this fixed collar and the sleeve 49. A nut or head 52 on the end of the rod 19 limits the movement of the sleeve.

The governor is contained in a closet. case 53 which is bolted to the'torward end 01": the crank case and the lever at? and its connections are also contained in a closed case 5 suittbly connected with the forward end of the case It will be seen that these two casings, together with the main casing entirely inclose the governor and its connections with the exception of the rod 19. This rod inclosed by a tube one end of which fits closely a circular opening in the easing 53, while the other end fits an opening in a casing 56, forming part of, or connected to, the mixture pipe 13, the casing 56 being adapted to inclose the crank 18. It is desir able to prevent. any parts which may become broken or loose from the governor from entering the compartment of the casein which the gear 25 and its connecting gears run and I therefore separate the governor compartment from the gear compartment by a partition or diaphragm 57 which, as shown, is bolted between the casings 28 and 53 and ha a circular opening fitting closely to the di. c 30, the diaphragm and disk fully separating the govern r and gear compartments. The governor is thus -tally inclosed in the casing 53 and it can not; be tampered with without removing this case. The movable connections between i'lli governor and the thr ttle valve it: are also wholly incloscd, as shoe n. The parts when thus assembled are d signed in he sealed so that access to the ,Q'ovct'nm and its connections can not be had ithout lomwledge of the owner or means of the cup 34,

As shown in Fig. l, a sealed wire 58 prevents rcmoval of the nut 59 which holds the casing 56 in place and also prevents tamporing with the valve controlling the bypass 20. Another scaled wire ht) prevents removal of one of the bolts (=1 which holds the casing 5i in place and also prevents re moval of the pin G2 which holds the tube iii-place. Still another sealed wire G 5 prevents tampering with the valve 2?) controlling the hy-pass Other sealing wires may be added if addit onal swau'ity be deemed necessary. The spring 51 serves to cushion thcaction of the gm'crnor upon the throttle valve, preventing shock to either of the parts or their connections when the valve is fully closed due to a sudden increase of speed of the motor. Tt will be noted that the adjusting sleeve. 2:37 extends through the wall of the governor housing, thus permitting of the adjustmentof the governor without opening its casing. It will be further noted that the adjusting means is-securel y housed and sealed and can not be tampered with without breaking the seal. I

The operation of the invention will be obvious from the foregoing description and need not be reviewed in detail. It will be evident that I have provided means for automatically controlling the maximum speed with which the engine of a motor vehicle may be operated and that I have also inclosed these means so that they may not be tampercd with. andso that the breakage of certainparts of the mechanism will not atfeet injuriously other moving parts thereof. Having described my invention what I claim and desire to secure by Letters-Patent. is.
